To all whom it may concern:

Be it known that I, EPPA H. Rronfa'oitizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Filling-Thread- Cutting Mechanism for Weft-Replenishing Looms,of which the following is a specification.

My invention relates to a fillin thread cutting mechanism for weft repi enishing looms which have a magazine for superosed bobbins or filling carriers, and transerring mechanism to transfer a bobbin from the magazine into the active shuttle, on the ractical or substantial exhaustion of the ling on the bobbin in said shuttle.

My filling thread cuttingme-chanism is adapted to cut the filling thread on the substantially exhausted bobbin, which is to be removed from the active shuttle, and to hold the end of the'filling thread, which leads from the cutter to the selvage of the woven fabric.

The object of my invention is to provide a filling thread cutting mechanism of imable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :Figure 1 is an inner end view of a detached portion of a. magazine, and the transferrer mechanism, and a. sectional view of the breast beam with my improvements in filling thread cutting mechanism combined therewith; the broken lines indicate the operative. position of the shuttle feeler. Fig. 2 corresponds to Fig. 1, but shows some of the parts shown in Fig. 1,;in a difl'erent position, and also shows a'eectional view of the lay beam, as it moves toward the breast beam, Fig. 3 is a plan view of some of the parts shown in Fig. 2,

looking in the direction of arrow a, same .on line 7, 7, Fig. 6, looking in the direction of arrow 0, same figure.

In the accompanying drawings, 1. Fig. 3, is a portion of a loom side or end frame, 2 is the breast beam, and 3 a stand mounted thereon, which forms a support for the magazine 4, (Figs. 1 and 2).

5 is the lay beam, 6, Fig. 3, a. portion of the stationary shuttle box on the end of the lay, 7 a part of a shuttle. and 8 a part of a bobbin having filling 9 thereon. which leads from the shuttle 7 to the selvagc of the woven fabric, not shown.

10, Figs. 2 and 3. is the transfcrrer arm, having its hub 10 mounted on a stud 11 on a stand 3. Extending downwardly from the hub 10 are the forked arms 12. which are adapted to carry, at their lower ends, the dagger or latch, not shown, in. the usual way which adapted to be engaged by the hunter on the lay, not shown, to operate the t-ransferrer arm 10. to transfer a fresh bobbin from the magazine into the active shuttle.

A stand 13 of the magazine has a stud 14 at its lower end. see Fig. 3, on. which is loosely mounted the hub 15' of an arm 15, which has secured thereto the shuttle feoler 16. A second arm 15" on the hub 15, has pivotally connected thereto the lower end of an upwardly extending connector 17, which, through the operation ofthe trans ferring mechanism, not shown. on the sub stantial exhaustion of filling in the active shuttle. moves downwardly the shuttle feeler 16. as shown by broken lines in Fig. 1.

All of the above mentioned parts except the shuttle feeler 16. mav be of any usual and well known construction.

I will now describe my improvements in filling thread cutting mechanism. Uponthe breast beam 2 is in this instance secured a stand 18. which forms a bearing for a horizontallv extending bar 19. The outer portion 19 of the bar 19 is of circular shape. and is guided at its outer end in an opem ing in a stand 18at 18C, A'helically coiled expansion spring 20 encircles the circular portion 19' of the bar in, and bears at one end against the end 18, and at its other end against the square shaped end on the bar. If and acts to yieldingly move and hold the bar 19 in its inward position. and toward the lay 5. The stand 18 has a boss 18 on its upper side, which forms a hearing for a horizontally extending shaft. 21, which has its other end journaled in a boss 2 on the stand 3, see Fig. 3. The outer end of the shaft 21 has secured thereon a rat het. wheel 22, which is adapted to be engaged and on erated by a pawl 23, which has its hub 23 pivotally mounted on a stud on the end of the arm 12, which arm extends downwardly from the hub 10' ot' the transferrcr 10.

On the operation of the translerrer l0, and the downwardly extending arm 12, the pawl 23 thereon will operate the ratchet wheel 22, to revolve the shaft 21 a certain amount. The inner end of the shaft 21 has secured thereon the pulley 24. which is preferably grooved to receive i belt 25, which passes from said pulley 24 around a small pulley 26, loosely mounted in this instance on a bolt 27 secured to an otlset arm 19 on the horizontally extending bar 19. The hub 26, see Fig. 6, on the pulley 26, has rigidly connected thereto a circular knife blade or disk 28, Which is preferably toothed. as shown. and adapted to hold the filling thread to he cut, and to carry it upwardly, in the direction shown by the arrow in Fig. 4, when the pulleys 24 and 26 are. revolved, through the operation of the transltu'rer arm above described. The filling is in this instance carried toward a knife blade 29. to be severed thereby. The knife blade 29 is secured by a. screw 30 to the head 19', and is yieldinglv held against the rotary cutter or circular knife 28.

To hold and clamp the end of the filling thread, which passes from the cutter to the selvage of the fabric, 1 provide an arm 31. Fig. 4. which has its huh pivot-ally mounted on a bolt 31' on the end 19" of thehar '19. A spring 32 is secured in this instance'u'pon the edge of the bar if). by :1 screw 32', and.

is forced downwardlv by an adjusting screw 33, and acts to vieldin rly hold downwardly the arm 31. The end of the arm 31 has a boss 31', see Fig. 5, and a bolt 34 in said boss has loosely mounted thereon a small pulley 35. adapted to guide a belt 36, which passes forwardly and around a similar pullev 37, see Fig. 4, mounted on a stud 38, which is adjustably secured to the bar 19, in this instance through an elongated open ing 19 in said bar, see Fig. 7. The end 19 of the bar 19 is in this instance provided with a projection 19*. see Fig. 4, over which the belts 25 and 36 pass to h d tlwm in contact and hold the end of the Fai ing thread, which is led in between said belts.

The shuttle feeler 16, which, upon the hstruliat exhaustion of a bobbin, is oprnted y the transtcrrcr mechanism, and is moved downwardly from the position shown by Full lines, to the position shown by broken lines in Fig. l, to feel for and il1dicatethe proper position of the shuttle, is provided in this instance with means, which are adapted to positively carry the filling thread toward the rotary cutter ,28. The teeter arm 16. see Figs. 1, 2, and 3, has in this instance an outwardly extending projection 16. carrying a stud 39 at its end, on which is 'pivotally mounted the hub 40 of a. downwardly extending arm 40, see Figs. 1 and. 2. The lower end of said arm {10 carries a stud 4], to which is pivotally connected one end of a rod or connector 42; the other end of said connector 42 is pivotally connected to a stud 43, which is ada ted to loosely slide in an elongated. slot, 16 in the inclined feeler end 16 of the feeler 16. The stud 43 has loosely mounted thereon a plate 44. which is provided with a stud 45, which also slides loosely in the slot 16". The slot 16 is curved or turned upwardly at its end 16*, which causes a quarter turn movement of the plate 44, when said plate is moved toward the front; of the loom, as shown in. Fig. 2. The late 44 has its rear end hook shaped at 44 and is adapted to catch the filling thread 9, when the plate is moved forwardly, to carry the filling thread toward the rotary cutter 28. A sliding movement is imparted to the hook plate or lever 44, on the advance of the lay to its front; position, through the engagement of the end of the lever 40. or a. roll 46 thereon, with an inclined projection 47, which is secured to the rear wall of the stationary shuttle box 6, see Fig. 3. A helically coiled contraction spring 48, has one end connected to a pin 49 on the level 40, and its other end, connected to a lug 15" on the arm '15, see Figs. 1 and 2, and acts to move haokwardly the arm 40, to its inoperative position shown, by full lines in. Fig. 1. i

It, will be understood that the details of construction of my improvements may be varied if desired.
